A+ grade SSL Security

To get a A+ grade on ssllabs.com with your InterWorx is pretty easy just follow our step by step guide below.

nano /etc/httpd/conf.d/vhost_domain-name.conf

scroll down to: <VirtualHost your-server-ip:443>

Add the following under that tag: Header add Strict-Transport-Security "max-age=63072000;"

Or if you have a wildcard SSL: Header add Strict-Transport-Security "max-age=63072000; includeSubDomains"

Now go to the bottom of the file you should see: SSLEngine on

Under that add the following:

SSLProtocol All -SSLv2 -SSLv3
SSLHonorCipherOrder On

You should see SSLCipherSuite RC4:HIGH:MEDIUM:!SSLv2:!ADH:!aNULL:!eNULL:!NULL:!LOW Comment it out with a # before it.

Add below it the following code:
SSLCipherSuite ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-DSS-AES128-SHA256:DHE-DSS-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA:!DHE-RSA-AES128-GCM-SHA256:!DHE-RSA-AES256-GCM-SHA384:!DHE-RSA-AES128-SHA256:!DHE-RSA-AES256-SHA:!DHE-RSA-AES128-SHA:!DHE-RSA-AES256-SHA256:!DHE-RSA-CAMELLIA128-SHA:!DHE-RSA-CAMELLIA256-SHA

Or try:
SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS
or even: https://wiki.mozilla.org/Security/Server_Side_TLS

Save that file and restart Apache: service httpd restart


EXTRA

nano cd /home/username/yourdomainname.com/html/.htaccess

Add the following:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTPS} off
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</IfModule>
